The Planck Catalogue of Galactic Cold Clumps

Title:
The Planck Catalogue of Galactic Cold Clumps

Speaker:
Dr. Ludovic Montier (CNRS, IRAP, Toulouse, France)
Abstract: We have combined the Planck-HFI and IRAS maps to perform an all-sky detection of the cold submillimetre Galactic sources over the whole sky, to build the The Planck Catalogue of Galactic Cold Clumps, counting 13188 sources. I will describe how we proceed to build this catalogue using an original multi-frequency detection method, and how we characterized this population of objects using new distance estimates for one third of them. I will finally discuss the results provided by the Herschel Galactic Cold Core follow-up Key Programme of about 350 PGCC sources, yieldings important clues about the early phases of the star-formation.

       Space Science Colloquium
Date:       16:30-17:30, 1 April (Wed), 2015

Speaker:    Toshio Fukushima (National Astronomical Observatory Japan)
Title:      Gravitational Field of Apple, Banana, and Crepe (ABC)
Abstract:
Funny objects are flying across the universe. Some planets recall
apples, some asteroids are banana-shaped, and Saturnian rings look
like crepe. If you (or a space mission) want to get close to, move
around, and/or land on them, you need to estimate, measure, and/or
analyze their gravitational fields. Nevertheless, the routine recipe
named the spherical harmonic expansion does not always work
due to the curse of Brillouin, who is famous for Brillouin scattering
and stands for B of the WKB approximation. This talk rephrases the
author's hard days to tackle this fundamental problem as a sort
of fairy tale. If you prefer a serious story and/or detailed information
including the PDF of academic articles and related Fortran programs,
